favorite cnidarian? theyre ma favorite phylum so id love to hear your favorite. or whichever you feel like talking about. also, sorry for reblogging a ton from you. big fan of the random marine facts.
Aaaaaa this is so hard. The phylum Cnidarian includes organisms like jellyfish, anemones, hydras, corals, and hydrozoa.
My favorite class is definitely Scyphozoa which is the free swimming true jellyfish. What interests me most about jellyfish is their nematocysts (stinging cells), so if I had to pick, I suppose I would pick the most deadly one- the Box Jellyfish.
Tumblr media
Cubazoa or Box Jellyfish are (as the gif says) the most venomous marine animal (that we know of). Like other jellyfish, they deliver their potent venom via nematocysts. Nematocysts are touch sensitive, when an organism brushes agains the tentacles, a stored thread with a barbed bob are released. These latch onto the organism and release toxin.
Tumblr media
What makes the Box Jellyfish venom so deadly is that it contains toxins that attack the heart, nervous system, as well as skin. It's so potent that people have been known to suffer heart failure or go into shock and drown before they reach the shore.
Thanks for the ask!

Synalpheus Regalis or Sponge-Dwelling Snapping Shrimp!
On land, we are all familiar with the eusocial behaviors of bees, but did you know that there is one genus of marine creatures that exhibit these same behaviors?
Sponge-dwelling snapping shrimp (aka pistol shrimp) are, according to Nat Geo, the bees of the sea! These tiny shrimp host the inside of sea sponges and live in colonies of about 300 members. The queen will reproduce while the eggs/babies are cared for by the colony. Guard shrimp also protect the queen and the colony from predators. This altruistic behavior exhibited by these shrimp is a strange and beautiful act that is continually being studied by scientists!
